I am not in total disagreement with that. A hardcore gym is meant to hardcore bodybuilders. Newbies can always choose other gyms to built some foundation.
It's might help to create a certain atmosphere, but they're always strong members with antisocial behaviour (talking loud, not re-racking the weights, etc).
It's different tho in a basement gym where I train every now and then, and I think the reason is more social control.
